cla ms. (01. 2212:1017- My invention relates to window structure and has'particular reference to the two sash type in contradistinction to What is known as the casement windowI 1 5 An object of my invention is to not only eliminate the use of the conventional sash weights, means for doing which I have disclosed and claimed in my copending application, but to provide window sash structure'of a particularly sim-' ple, durable, and inexpensive type embodying buttwo distincturiits. In this way the "various units'are interchangeable should that necessity occur.

A still further object of my invention is to provide meansassociated with one of the sashes and adapted to cooperate with the other whereby the window may not only be locked in its closed position, but whereby the two sashes may be locked in any relative position. This is extremely advantageous where it is desirable to lower the upper sash when the upper sash is somewhat too high to reach easily. In lieu of exerting oneself to reach the upper sash and lower it, the lower sash may be raised to whatever extent it is de- -sired to lower the upper sash, the sashes locked together, and the lower sash closed once more carrying with it the upper sash.

Various other meritorious features of my invention will be apparent from the following description taken in conjunction with the drawings wherein like numerals refer to like parts throughout the several figures and wherein:

Fig. 1 is a front view of my assembled window structure, Fig. 2 is a perspective of my inner sash frame members,

Fig. 3 is a front elevation of my locking mechanism,

Fig. 4 is a section through line 4-4 of Fig. 6,

Fig. 5 is a vertical elevation partly in section illustrating the operation of my locking mechanism, and

Fig. 6 is a similar view illustrating a slightly different embodiment of the locking mechanism.

In Fig. 1 I have illustrated my complete assembly which includes the side frame or jamb members 10 and 12 and the sill and top head members 14 and 16 respectively. Flexible metal guide strips 18 and 20 are secured to each of the 7 members 10 and 12, extending longitudinally along the length thereof and adapted to be received within grooves along the outer edges of each of the sash members. 7 Each of the said sash members includes frame elements 22 which are rolled from sheet metal,

preferably into the form illustrated in the other figures, and securedto one another as illustrated in Fig. 1- by means of welding or soldering.

Cross -frame pieces 24 of identical structure'- are' secured in the manner illustrated in Fig. -l to the outside frame members 22. The structure of these cross frame membersis more clearly illustrated in'Fig. 2. 'They'are also preferably rolled from sheet metal in the form illustrated which'constitutes a'channel shaped T-member.

The horizontal 'unit' 24a 'is punched as indicated at 2'8 and thevertic'al unit 241) is punched as at 30 prior'to the rolling operation for the purpose" of permitting 'a tight joint when inserted within the outer frame members 22. It is to be noted that the side walls 32 and 34 of these channel-shaped frame members are tapered and by reason of the material from which they are rolled this channel is somewhat resilient, permitting the side walls to be spread apart slightly upon the insertion of a memberto be described hereinafter.

Still another feature of the taper on these channel shaped frame members resides in the fact that they materially assist in forming a tight union, with the aid of the putty, between the frame and the glass pane which is inserted in the bead 36 formed along the outside of each channel.

Secured to the upper frame member 22 of the lower sash is my locking mechanism. This consists of a flange 38, fastened to the frame member 22 by screws 40 and having upwardly extending arms 42 and 44. A locking handle 46 is rotatably journalled on a pin 48 extending between the arms 42 and 44, which member includes an arcuate prong shaped member 50 which is adapted to function in a manner to be described. In Fig. 5 I have illustrated one method in which my locking mechanism may operate. Here the prong shaped extremity 50 upon downward movement of the handle 46 is forced in between the tapering side walls 32 and 34 of the channel shaped frame member 24b. The metal of which these frame members are made possesses sufficient flexibility as already stated to grip the said prong 50 with sufiicient power to retain the two sashes in any relative position to which they may be adjusted.

A somewhat modified form of locking mechanism is illustrated in Fig. 6 wherein a plurality of dogs or pins 52 extend in spaced apart relation across the channel between the side walls 32 and 34. As the handle 46 is lowered and the prong 50 enters into the channel it hooks around whatever one of these pins 52 chances to be in the proper position to receive it. In this way a positive locking means is secured and inasmuch as the vertical frame 241) may be provided with such pins at small regular intervals throughout its length the upper and lower 1. Window structure comprising, in combination, an upper and lower sash including vertical and horizontal frame members of channel shaped construction, and movable means supported by said lower sash and adapted to cooperate with the channel shaped frame of said upper sash to retain the two sashes in any adjusted position.

2. Window structure comprising, in combination, an upper and lower sash each including frame members of channel shaped construction, a plurality of pins secured in horizontal position across the channel of the vertical frame in said upper sash, and a movable locking unit supported by said lower sash adapted to cooperate with any one of said pins to lock the two sashes together.

3. Window structure comprising relatively movable upper and lower sashes, said sashes including horizontal and vertical frame members of channel shaped construction,.and a member pivoted to said lower sash having a portion adapted to frictionally engage the side walls of a-chanjusted position by frictional resistance.

4. In combination with an upper and lower window sash including channel shaped frame members, the walls of said channel being slightly flexible, a manually manipulable locking member secured to one of said sashes and adapted to frictionally cooperate with the resilient side walls of one of said frame members to lock the two sashes against relative movement.

5. In combination with an upper and lower window sash, one vertically extending frame member of one sash being channel shaped in cross section and having resilient side walls, and a manually manipulable member supported by the other sash member, one vertical extremity there- 'of adapted to be swung into frictional seating engagement with said channel shaped frame member at any point along the length thereof to retain the sash members in any relative position to which they may be adjusted.

6. In combination with an upper and a lower slidable window sash, means for fixedly positioning said sashes in any relative position to which they may be adjusted comprising a pair of cooperating members, one of said members extending longitudinallyalongthe length of one of said sash members, the other of said members being movably positioned by the other of said sashes in cooperating relation to said longitudinally extending member, one of said cooperating members including a yieldable portion adapted to cooperate with the other of said members to provide frictional resistanceto movement between said sashes at any relative position to which they are ad.- J'usted and operable to lock said sashes together to travel as a unit. a
